For x number of resistors of resistance 176 Ω, the equivalent resistance of the resistors connected in parallel is given by Ohm's law as \(V= IR\)
\(R= \frac VI\)
Where,
Supply voltage, \(V= 220 \ V\)
Current, \(I = 5\ A\)
Equivalent resistance of the combination = \(R\), given as
\(\frac 1R = x \times (\frac {1}{176})\)
\(R = \frac {176}{x}\)
From Ohm's law,
\(\frac VI = \frac {176}{x}\)
\(x = 176 \times \frac IV \)
\(x= 176 \times \frac {5}{220}\)
\(x= 4\)
Therefore, four resistors of 176 Ω are required to draw the given amount of current.
Resistance is the measure of opposition applied by any object to the flow of electric current. A resistor is an electronic constituent that is used in the circuit with the purpose of offering that specific amount of resistance.
R=V/I
In this case,
v = Voltage across its ends
I = Current flowing through it
All materials resist current flow to some degree. They fall into one of two broad categories:
Resistance measurements are normally taken to indicate the condition of a component or a circuit.
